Hi Shapeways fans, Big Chop is a twisty puzzle like Rubik's Cube. It was named by Bram Cohen. The object of the puzzle is tor scramble the 120 pieces and try to turn them back. Twisty puzzle fans will be horrified to learn about the mechanism. There is a steel ball inside and all pieces have magnets that hold them around the ball. There is also a pedestal to support the puzzle. A special tool is needed to turn the puzzle. Buy the puzzle. Or perhaps not, given its awkward operation. https://www.shapeways.com/model/65458/big_chop.html Watch the YouTube clip. https://www.youtube.com/watch?v=IKXnI7ed0ZE Look at the photos below. Enjoy!
